If you don't understand your assignment and you can't reach your boss, what would you do?

This question is seeing how you react to ambiguous situations. Also it checks to see how resourceful you are. The best way to answer this question is to provide step by step actions you would take in this situation.

There might be a better answer, but in my experience many interviewers are looking for a process of reaching a goal. In this example, it shows each step from beginning to end. Feel free to add or change these steps after thinking about it.
